DEEP-WELL ruivIPING MEOIIANISM.

Application ledctober 1, 1924.A Serial No. 741,085.

My invention relates to the operation of deep-well pumping` mechanism. YHeretoifore it has beenl common practice to operate the pistons of deep well pumps by means of a gear mounted in an oil tank or reservoir'in thelower portion of a vpower head or casing, such gear being connected. by a pitman with a vertically reciprocating cross-head con of a pump rod to which the pistons are attached, the gear itself being driven by means of a pulley mounted on shaft extending' through one side ot the power head casing and operatively connected with the gear by a pinion carried by the shaft. The pulley has been driven by a belt Jfrom a steam engine or other source ot power separate from the power head. To guide the cross-head during its reciprocation a guiderod hasl been` providedv disposed vertically in the power head. A power head of this description is shown and described in my pending application, Serial No. 655,A75, filed August 3, 1923. The object of my present invention is to provide an improved construct-ion and arrangement for operating the piston ot pumping mech anism ot the type referred to by which the motive power will be incorporated as` a part y head unit, and by which also of the power kind will be iin-provedl in apparatus of this other respects, ashereinafter accomplish this object as 'illustrated inthe accompanying drawings andas hereinafter described. That I regard as new is set forth in the claims.

In the accompanying drawingsV- Fig. 1 is an end elevation of my improved apparatus Fig. 2 is a central vertical section substantially on Vline 2-2 of Fig. 1, the motor being shown in end elevation;

Fig. 3 is a bottom plan view of the motor support. the guide rod being shownl in sec .tion and Fig. 1 is a sectional viewv showing a moditied .form of motor support.

Referring to the drawings,+5 indicates the traine or casing-ot the power head, the

lower portionot which forms an oil reservoir, as indicated in Fig.l2, the inner wallrv of such reservoir being formed by a vertical partit-ion 6. lMounted in said casingon a shaft 7 is a driving gear 8 which is rotated by means of a pinionl 9 mounted on a shaft 10 jonrnaled in suitable bearings in the side pointed out. I,

portions ofy the casing 5, preferably in the manner shown and described in my pending application hereinbeiore referred to. The

`shaft 10 also carries' al pulley 11 as best shown in Fig. 2.

`Within the casing stepped in asuitable socket formed in a boss 1-3, while its lupper end extends through a 1boss 14 at the upper portion of the casing by a yset screw 18. r Said set screwalso en-v gages the upper vend of the guide rod 12 and holds it in place.

Mounted to reciprocate vertically on the guidel rod 12is a pump-actuating member.

in the form of a crosshead 19 which is provided at one side with an arm connected by a pitman'21 with a wrist pin 22 carried by the ygear wheel 8, so that rotation of gearwheel reciprocates said cross-head. At

its opposite side said 'cross-head is provided with an arm 23 to which is connected the upper end of a piston rod 2A which carries the usual pistons 25 by whichthe' water is elevated.

The pulley 11 is driven by means of an electric niotor 26 which is mounted on a sup--r port in the form of a base plate 27 shown being of such size that said base plate mayY be ittedon the projecting upper end ofthe guide rod 12, where it is secured by a bolt 29, as best shown in Fig. 2. The `motor is ksecured to the base plate 27 by bolts 30. V The armature shat't 31 ot the motor 26 carriesa pulley 32 which is connected by a belt 33 with the pulley l1, so that the latter pulley is'ldr-iven by the motoi. The belt 33 is held taut vby a belt tightener inthe torni ot a roller 34- mounted onva crank 35 carried" bv an arm 36 which is, pivoted upon the shaft 10. so thatthe roller 3A mayl swing in the veiticalplane ot the belt A spring 37 having one endconnected with the arm 36 5 is a` verticallyy disposed Y guide rod 12, the lower end of which is Figs. 1, 2 and 3. Said base plate is prosaid 1 Voperative relation to the i power.

and the other end with the motor support 27 serves to pull the roller 34 against the belt 33 and keep it under proper tension, as best shown in Fig. 2. v

In F 4t I have shown a modification of the motor support in which instead of using the base plate 27 having a hole at the center to receive the 'upper end of the guide rod l2, I employ a. base plate 38 havingl a split socket 39 at one margin in which the upper end of the guide rod l2 is adaptedto fit. By means of a bolt 40 atending through the separated lips of said socket the socket may be contracted and clamped on the guide rod l2 so that the base plate is firmly secured thereon;

1I" rom the foregoing description it will be seen that the motor is mounted on vtop of the power head either in alinement with the guide rod, or sultistantially sorso vthat the operating mechanism maires a very compact unit. rEhev motor is easy to install, and the construction described provides a support for the motor without any additional machine work on the power head casing. Moreover, it makes practicable the carrying in stock of frames of one design that can be used either as a` inotoredriven unit, such as that shown and described, or can be used in connection with a source of power separate from the power head, as described in my said pending application.y In the latter case the spring 37 would be omitted, and the belt tightener arm 36 would be swung down into belt connecting the `pulley ll with theeugine or other` source of By securing the guide rod i2 to the top and bottom of the casing, the casing is strengthened and made better capable of supporting the burden imposed upon it by mounting the motor asdescribed.
